There is a whole industry right now devoted to attacking organic food. Every study that suggests maybe organic food is better or healthier or greener or is in any way preferable to conventional or GM food gets attacked by the PR machine of conventional food growers. This has been going on for at least 20 years (look at the massive media attack on DIET FOR A POISONED PLANET back in the mid-90s). But a simple, easy to replicate experiment--and common sense--makes it pretty clear that organic food is better and better for you.
Is Organic Better? Ask a Fruit Fly - NYTimes.com
The research, titled “Organically Grown Food Provides Health Benefits to Drosophila melanogaster,” tracked the effects of organic and conventional diets on the health of fruit flies. By nearly every measure, including fertility, stress resistance and longevity, flies that fed on organic bananas and potatoes fared better than those who dined on conventionally raised produce.
While the results can’t be directly extrapolated to human health, the research nonetheless paves the way for additional studies on the relative health benefits of organic versus conventionally grown foods. Fruit fly models are often used in research because their short life span allows scientists to evaluate a number of basic biological effects over a relatively brief period of time, and the results provide clues for better understanding disease and biological processes in humans.
For her original middle-school science project, Ria evaluated the vitamin C content of organic produce compared with conventionally farmed foods. When she found higher concentrations of the vitamin in organic foods, she decided she wanted to take the experiment further and measure the effects of organic eating on overall health.
